The Huawei P9 is the Chinese smartphone maker's latest flagship device.
The fingerprint sensor can also be programmed to answer calls and swipe through pictures.
Huawei is hoping the dual camera (colour and black-and-white sensors) and a tie-in with Leica will attract snap happy users.
The smartphone runs Android Marshmallow 6 with Huawei's custom user interface over the top.
